JOHN V. H. DOUBLER, OF ROCKFORD, ILLINOIS, ASSIGNOR TO THE DIAMOND FURNITURE COMPANY, OF SAME PLACE.

CHAIR.

SPECIFICATION forming part of Letters Patent No. 460,568, dated October 6, 1891. Application filed February 28, 1889. Serial No. 301,557. (No model.)

To aZZ whom it may concern.-

Be it known that 1, JOHN W. H. DOUBLER, a citizen of the United States, residing at Rockford, in the county of lVinnebago and 5 State of Illinois, have invented a certain new and useful Improvement in Chairs, of which the following is a specification.

This invention relates to the class of chairs commonly called platform or pedestal 1o rockers, and it consists of certain new and useful features of construction and combinations of parts hereinafter described, and pointed out in the claim.

Referring to the accompanying drawings, [5 which form a part of this specification, Figure 1 is a side elevation of my improved chair. Fig. 2 is an enlarged detail elevation of the central portion of a rocker of the same and the upper portion of a pedestal 2o whereon it operates. Fig. 3 is a view of a vertical section through the dotted line x x of the parts shown in Fig. 2. Figs. 4 and 5 are front and side views of rocker and connecting-plates, to be described hereinafter. 2 5 Like letters of reference indicate corresponding parts throughout the several views.

A represents pedestals consisting, preferably, of the bases A, upright portions A and top pieces A The pedestals may be secured together by means of cross-pieces or in any other suitable manner and project above the bottom of the chair-seat.

B B 13 represent, respectively, the seat, side pieces, and back of the chair, which together form the chair-body.

B represents arms secured to the chairbody in any suitable manner.

O represents chair-rockers located between the bottom of the seat B and the arms B of the chair, secured to the sides of the chairbody in any suitable manner and resting operatively upon the upper ends of the pedestals A.

D represents rocker-plates having holes D 5 D therein to admit screws D E, the former securing the same to the rockers O.

E represents connecting-plates having slots E and holes E therein to admit screws, and are provided with lugs E which enter the countersinks A in the pedestals A. The bifurcation e of the slots E in the connectingplates alternately admit the screws E as the chair is rocked back and forth. The connecting-plates E are thereby required to oscillate only very slightly and are subjected, together with their connections and attachments, to minimum strain and wear. The connecting-plates are pivotally mounted upon the pedestals A by means of screws E and are connected with the rockers O by means of screws The office of the connecting-plates E is to retain the rockers O upon the pedestals A and at the same time permit them to operate freely. The lugs E by engaging with the sides of the countersinks A prevent the 6 5 chair-body from having too much back and forward motion. The dotted lines in Fig. 2 sufficiently indicate the movements of the rockers O,rocker-plates D, and connectingplates E while the chair is beingused.

F represents shields for covering the outside of the rockers G and upper outside ends of the pedestals A. The shields are secured to the rockers by means of screws F, inserted through the former into holes F in the chairbody.

WVhenever it is desired to remove the chairbody and rockers from their pedestals, the screws E may be removed by inserting a screw driver through the holes F in the shields F.

I claim and desire to secure by Letters Patent In combination,in a pedestal rocker, a pair of pedestals, properly secured together, projecting above the bottom of the seat of the chair and having their upper ends adapted to receive and operatively support a pair of rockers, a pair of rockers, the rocker-plates secured to said rockers, the connecting-plates having longitudinal slots E and holes E therein and arranged to swing on the pivots E and being limited in their movements by the lugs E inserted into the holes A for retaining said rockers upon said pedestals, a chair-body 5 suspended from the rockers between the pedestals, and suitable means for securing all of said parts operatively together, substantially as specified, and for the purpose set forth.
